Here we have a system of equation like this:
[tex]A+B=11\\
0.4A+0.7B=5.9[/tex]
from the first equation we get:
[tex]A=11-B[/tex]
Substitute in the second equation we get:
[tex]0.4(11-B)+0.7B=5.9\\4.4-0.4B+0.7B=5.9\\0.3B=1.5\\B= \frac{1.5}{0.3}=5 [/tex]
Substitute i the first equation again we get:
[tex]A=11-B=11-5=6[/tex]
We deduce that:
[tex]A > B[/tex] A is bigger than B.
